Subclasses should implement this method

[c3rry]

I am attempting to establish my sample in the ClearMap2 GUI, but I am running into an error after selecting my source folder, which contains two sub-folders each containing a sequence of tiff files for both the cFos and Autofluorescence channels respectively. We are unfortunately running into the following error log:
